The first step is to check the bolts that hold the control arm to the frame. If any of the bolts are loose, tighten them up.

If the bolts are tight, the next step is to check the bushings. If the bushings are worn out or damaged, they will need to be replaced.

Finally, if the control arm is rusty, you can try to clean it up with a wire brush. If the rust is too severe, you may need to replace the control arm.
